About carbon steel
Carbon steel is iron with up to about 0.35 % carbon and 1–1.6 % manganese, and no deliberate chromium, nickel or molybdenum. It is the default material for piping in water, steam, oil, gas and general process service from about −29 °C up to roughly 425 °C.
Reference information compiled from the published standard for convenience. It does not replace the current edition of the governing standard, which takes precedence.
